Hi,

When HIGHMEM is used, memory pages are mapped to virtual addresses

And they don't have to. If you have a highmem page, use kmap to get
temporary virtual mapping. On the other hand most of the drivers should
never see a highmem page.
I would like to know who works on APUS as well.
I do currently.

bye, Roman
